Togol, it's hard to suggest, not knowing what you already have access to. If you already have a clamp-on ammeter, that Fluke 110 looks like a good choice. But if you don't have a clamp-on, consider one that also comes with test leads for other DMM functions. The 110 max is 10A AC or DC. I take a Fluke 187 into the field but I can always bum an Amprobe if I need one.
